How about after you were stuck in the cold or the heat and because you were you broke the back of the Germans offensive during the Battle of the Bulge or ejected the Japs from Guadacanal and sent the Imperial forces of Japan reeling backwards inevitably towards Hiroshima and Nagasaki. Sounds good to me.
ordinary foot soldier is stuck there, living one day at a time, with death tugging at his elbow. Good war, that doesn't sound good to me.
The men on the lines didn't have time to see that their tactical efforts would produce strategic results. But the freedom they brought whether foreseen by them or not at the time made their efforts part of a 'good' war.
Are you dissatisfied with the results? What's your point? War sucks so we shouldn't participate? If the results aren't factored in, no war could be seen as positive.
I am overjoyed by the results, but lets not pretend that however important the struggle, however morally just cause, a soldier or marine on the front lines cannot allow himself to think about grand strategy but only on survival - and killing the enemy, of course.
